By John Martin - March 19, 2022

What’s not to love about flat-faced dogs with their cute and wrinkly faces and squished noses? Flat-faced dog breeds or brachycephalic breeds with their squishy faces are super cute, loving and adorable. It’s no wonder that these breeds are popular with dog owners across the world.

What Are Flat-Faced Dogs?

Flat-faced dogs, officially known as brachycephalic dogs (“short head” in Greek) are squishy-faced dogs (some even say smushed faces) like Pugs, Bulldogs, Shih Tzus and Boston Terriers, to name a few, that have characteristic features such as a flat face, short skull and a short snub nose.

Bred for their cute looks, unfortunately, these adorable flat-faced dogs suffer from airway and breathing problems because of their squashed faces, among other health problems.

These flat-faced breeds are prone to brachycephalic airway syndrome, which makes breathing quite difficult, causing symptoms such as heavy breathing, snoring, breathing problems and a greater risk of suffering from heatstroke.

These dogs are vulnerable to eye problems and spinal problems and in general, have shorter lifespans compared to dog breeds with longer muzzles.

Nevertheless, despite all the health risks, flat-faced dogs are loved by pet owners because they make cute and loving pets. Research shows that this may be because of the resemblance of the facial features of these flat-faced dogs to that of human infants, triggering an emotional response and impulse to nurture.

So, if you’re thinking of bringing home a flat-faced pooch, then read on to know everything about the most popular flat-faced dog breeds.
